TYPE-WRITING MACHINE.

Specification of Letters Patent.

Patented Dec.. 9, 1919..

Application filed March 26,1918. Serial No. 224,716.

To all whom t may concern Be it known that' 1 LEWIS C. MYERS, a citizen of the United States, and a resident of the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Type-Writing Machines, of which the following is a specification.

*The present invention relates generally to typewriting machines and has more particularly reference to the margin controlling devices thereof together with means for effecting bell ringing and line locking.

In Patent No. 1,267,769 dated May 28, 1918 there is disclosed a typewriting machine of the visible type in which there are visible margin controlling means located in rear of the type bars and adjacent the front of the carriage and platen, said means consisting, in part, of two margin rails, one on each side of the printing center, thus affording between them passage for the type bars to the printing point. In that case, the left -v hand margin rail is rigid while the right hand margin rail is pivotally mounted on horizontal supports so as to constitute, in

effect, a rocking member by means of which bell ringing and line locking may be eii'ected.

The main object of this invention is to obviate the necessity of having a rocking -margin rail on the right hand side of the printing center and to this end consists, as one feature of the invention, in means associated with a rigid right hand margin rail whereby the traverse of the platen will actuate intrumentalities, in any adjusted position of the margin stop, to eect bell ringingV and line locking in the pioper manner,

Other features of the invention will appear as the speciiication proceeds.

In the accompanying drawings, the in-y vention is clothed in a concrete and preferred form. However, variations may be made without departing from the invention.

In said drawings:

Figure 1 is a top` plan view of a typewriting machine of the character shown in the patent granted to Edward B. Hess, No. 1,267,769, and here shown largely in diagrammatic outline with elements omitted for the purpose of more clearly illustrating the invention:

Fig. 2 is a vertical sectional view through the machine, showing the relative arrangement of the parts embodying my invention when the machine is viewed in cross section, unnecessary elements being omitted;

Fig. 3 is a view substantially similar to Fig. 2 but on a larger scale to more clearly indicate the construction embodying the in vention:

Fig. 4 is a detail plan view, partly in section and partly in elevation, of the right hand margin controlling device as shown in Fig. 1.

Fig. 5 is a sectional view on the line 5-5 of Fig. 1: and

Fig. 6 is a detail sectional view on the line 6-6 of Fig. 5.

1 indicates a frame work of any suitable construction, such as that generally employed in the well known Royal typewriting machine; and 2 is the dust shed or top plate, which covers, in a general way, the mechanism contained within the machine. 3 indicates suitable key levers such as are commonly employed; and 1 the type bars,

only one of which is shown to represent, in

a manner well understood, a series. 5 is a platen of suitable construction mounted, in any convenient manner, in a carriage 6 having a race way 7 and having suitable means, represented here by the member 8, for effecting case shifting. The shift mechanism employed is that of the well known Royal typewriter such as is described in Patent No. 1,227 ,438. 9 is a bell or gong, shown as being supported directly beneath dust shed 2 by means of a screw 10 which, in this instance, also serves to fasten a ribbon housing 11 in position. 12 is a line locking blade, carried by lever 13, extending transversely of the machine and normally held out of line locking position by means of a sprinoA 111, in a manner well understood, and whic when brought under locking surfaces 15 of the key levers, serves to line lock the entire series of keys.

16 is the left hand margin rail and 17 the right hand margin rail; 18, the left hand margin stop and 19, the right hand. margin `stop, while 2() and 21 represent stop blocks carried by the platen or carriage and having engagement with the margin stops in a manner to be hereinafter described. It willabe seen, especially from Fig. 1, that the margin rails are located one oneach side of the printing center, generally designated by 22; and that the dust sheds are so arranged as to afford free passage of the type bars 4 to and 'from said printing center. It will be understood from consideration of Fig. 2, that` margin rails 16 and 17 are located immediately in front of the platen and on either side of the printing center thereof and below a horizontal line and in front of a vertical line drawn through the axis of the platen. In fact, as here shown, said margin rails are below a horizontal line tangent to the underside, and in front of a vertical line ...tangent to the front side, of the platen. The

two margin rails 16 and 17 are mounted in any suitable manner upon the frame-work of the machine, a convenient method being here represented by screw 23 which latter also serves to hold the rack 24 in position. This rack may be Vconsidered as part of the margin rail. To cause stop blocks 2O and 21 to properly coperate with the margin stop they are, in the present instance, pivotally supported on horizontal pivots 25 and a spring 26 is utilized for normally urging the lower end 27 of said stop blocks into lowermost position in the path of the VmarginV stops on the rails. During normal traverse of the carriage, stop blocks 2O and 21 will be carried beyond the carriage frame and since they will consequently then occupy.y the lowermost possible position, they will project below the top surface of the dust sheds. For this reason, inclined surfaces located on top of the dust sheds, such as 70, are employed over which during the traverse of the carriage the stop blocks ride and thereby bring the lower surface 27 of said stop block into a position that is in the path and plane of the margin stops. There is a further advantage in this construction of stop block in that` it will be observed from Fig. 2, if the carriage and platen are moved into their shifted position, as indicated in dotted lines, the pull of spring 26 will maintain stop block 20, or 21, in proper relation to its margin stop. It will also be understood that by manipulation ofhandle 28 in opposition to the action of spring 26, the stop blocks may be moved upwardly out of the path of the margin stops to admit of additional writing at either end.

The right hand margin stop 19 is provided with a locking member 83 having teeth 34 at its inner end which serve to engage with corresponding teeth in rack 24 and which is actuated by means of a pin 35 engaged in an aperture 36 and extending npwardly through an elongated slot 37 in margin stop 19. Normally, the locking member 38 is urged into its locked position by means of spring 38 but the action of this spring is overcome, at will, by the operator by means of handle 39 pivoted at 40 and engaging the member to move it out of engagement with the teeth in rack 24. By these means, the right hand margin stop can be moved into any adjusted position. Suit-- ably mounted on the right hand margin stop 19 is a latch or locking member 41 supported on a vertically extending pivot 42 and provided with two engaging portions 43 and 44 and also with a downwardly extending projection 45 that passes through an opening in the dust shed and terminates in fork 4G. Extending beneath dust shed 2 is an actuating member here taking the form of a rock shaft 48 that extends horizontally and is suitably supported in the dependent lugs 49 that project from the underside of the framework. Mounted upon this rock shaft is a bail 50 with which the forked member 4G engages. lt will now be understood that if margin stop 19 is adjusted to any position within the limits of its construction. forked member 4G will slide on bail 50 and will provide operative engagement between the margin controlling device and rock shaft 48. Loosely mounted on said rock shaft 48 is a bell hammer 51, here shown in the form of a wire bent around said rock shaft and having a doubled-back portion that serves as a stop and. engages with the underside of the dust shed. The bell hammer is normally held in its uppermost position by means of spring 53. `Mounted fast on rock shaft 48 is a bell crank 54, one end 55 of which has a portion 5G bent over the. bell hammer so as to lower and depress it when thel rock shaft 48 is rocked in one direction. The other arm 57 of said bell crank is connected by means of link 58 to a vertically extending rock shaft 59 mounted in suitable bearings 6() in the rear of the machine and having a suitable connection, such as 61, by means of which it is connected to line lock sha'ft 18. It will now be understood that` when the carriage is moved in a left hand direction, stop block 21 will first encounter the engaging portion 43,- thereby turning the member 41 on its pivot 42 and causing the forked extension 4G to turn bail 50 toward the left in Fig. 2 thereby causing rock shaft 48 to turn and carry with it bell hammer 51; and, if stop block 21 passes beyond the point where it engages portion 48 of member 41, gravity will restore rock shaft 48 to its central position and thereby permit spring 58 to soundV the gong or bell 9 thereby indicating to the operator that the end of the line is being approached. As the carriage continues its traverse in the left hand direction, stop block 21 will next encounter engaging portion 44 and thereby swing the member 41 on its pivot 42 until said member 44 comes in abutting engagement with locking member 33. This will cause forked extension LG to move the bail in a direction opposite to that for bell ringing (to the right from position in Fig. Q) and will effect rocking of rock .shaft 4S thereby causing a pull to be exerted through link 5S to the vertically extending rock shaft which, in turn, transmits the motion and brings the line lock blade 12 under the surface of the key levers, thereby1 locking the machine. Should it now be desired to write additional matter, handle 28 is depressed thereby lifting the end 27 of stop block 2l and thus causing spring 14 of the line lock mechanism to restore the parts to normal position and out of line locking position. Spring 14 also tends to move rock shaft 48 into its central position, the movement of rock shaft 48 also being facilitated by the action of gravity.

The member 33 is also provided with a taper surface, as indicated in the drawings, (Fig. 6) so that as stopblock 21 is elevated to admit of additional writing, it will ride down said incline gradually and without shock to the parts; and; when drawing the carriage in a right hand direction, said stop block 2l will ride up said incline and admit of uninterrupted traverse of the platen in a right hand direction. I

The lefthand margin stop is of substan- ,tially the same construction as the margin stop 19 except that it is not provided with a lrocking member 41. In all other essentials,

however, it is the same in that it is provided with a locking member 33 that is manipulated by means of a handle 39, in the manner described in connection with the right hand margin stop. It will be understood (when actuating the usual carriage release mechanism) that during the right hand traverse of the carriage the stop block 20 will come in engagement with the member 33 of margin stop 1S, thereby preventing further advance of the carriage. Should it be desired to print beyond the point provided for by the adjustment of the margin stop, stop blockv 2O will be manipulated in a manner similar to stop block 21 carrying it over abutment member 33. IVhen the carriage then begins its left hand traverse, stop block 20 will ride up the inclined surface of member 33 and continue uninterruptedly in the left hand direction.
